MMSZ5248B-7-F Description

Short technical summary and product information.

The MMSZ5248B-7-F is a 500mW surface mount Zener diode designed by Diodes Incorporated. It provides a nominal Zener voltage of 18V with a ±5% tolerance, making it suitable for voltage regulation and reference applications. The device features a maximum impedance of 21Ω at the Zener test point and a low reverse leakage current of 100nA at 14V. The forward voltage drop is 900mV at 10mA. Power dissipation is rated at 500mW at a lead temperature of +75°C, and 370mW at an ambient temperature of +25°C. The operating temperature range spans from -65°C to +150°C, with a thermal resistance junction-to-ambient of 338°C/W. The diode is housed in a SOD-123 surface mount package, which is compatible with automated assembly processes. It is qualified to AEC-Q101 standards for high reliability, and is fully RoHS compliant, lead-free, and halogen-free. The part is supplied in tape and reel packaging with 3000 units per reel.
